The utility model relates to a measuring adjustable plate device for installing a track plate during the high-speed railway ballastless track building process. The device comprises a measuring robot, an industrial control computer, a station, a display and prisms placed at both sides of a cross beam of a speed adjusting reference frame, wherein conical telescopic mechanisms are respectively arranged at both sides at the lower part of the speed adjusting reference frame, each conical telescopic mechanism comprise a supporting rod, a telescopic cone with a step is arranged in the inner cavity of the supporting rod, and a clipping dummy club is correspondingly arranged between the circular supporting surface at the lower part of the supporting rod and the step of the cone. By adopting the measuring adjustable plate device, the bolt hole with good linearity is taken as the base line for measuring the adjustable plate, therefore, the working procedure of high-precision polishing for the track plate production is omitted, the problem of high production cost of the track plate is solved, the height is higher, the visual field is wider, and compared with the former survey station by which only one to two track plates can be measured, the measuring speed is greatly increased, four to five track plates can be continuously measured, and the measuring speed is increased.
